Series Circuits Online Test – Multiple Choice Questions and Answers Posted on April 16, 2024April 16, 2024 by engineer2 Comments 1. How will an open resistor affect a series circuit? Total resistance will decrease The open resistor will drop 0 V No current will flow in the circuit Current will flow around the open resistor 2. Kirchhoff’s voltage law states that: the voltages developed across each element in a series circuit are identical the sum of the voltage drops in a series circuit is equal to the total applied voltage the algebraic sum of the individual currents around a closed loop is zero the algebraic sum of the resistances is equal to the sum of the voltages 3. Power is defined as: the rate at which work is done work joules the conversion of energy 4. An 8-ohm resistor is in series with a lamp. The circuit current is 1 A. With 20 V applied, what voltage is being allowed for the lamp? 4 V 8 V 12 V 20 V 5. When a battery is connected to a series circuit, it delivers current based only upon: total resistance average resistance primary/secondary difference the polarity connections 6. With a total resistance of 3300 ohms and a 45 V source, if R3 is 1200 ohms, what will be its voltage drop? 10.90 V 32.72 V 16.36 V 15.00 V 7. The voltage drop across a series resistor is proportional to what other value? wattage rating the amount of time the circuit is on total resistance its own resistance 8. A string of resistors in a series circuit will: divide the source voltage in proportion to their values reduce the power to zero cause the current to divide increase the source voltage in proportion to the values 9. If series current doubles, then: voltage is doubled resistance is halved voltage is reduced resistance is doubled 10. An 8-ohm resistor is in series with a lamp. The circuit current is 1 A. With 20 V applied, what voltage is being allowed for the lamp? 4 V 8 V 12 V 20 V Loading … Question 1 of 10
